Specification of I'Letters Patent.

Application filed December 19, 1911.

Patented June 4., 1912.

Serial No. 666,790.

To all whom it may concern:

Be it known that I, THOMAS B. BUTTERS, a subject of the King ofGreat Britain, residing at 123 West Thirty-third street, New York, in the county of New York and State of New York, have invented new and useful Improvements in Anchors, of which the following is a specification.

This invention relates to anchors and more especially to that class where the fiukes may be folded in order to store the anchor within a very small space and where they can be released and allowed to operate when in use as will be more fully described in the following specification, set forth in the claims and illustrated in the drawings, wherein,

Figure 1 is a plan view of the anchor folded. Fig. 2 is a similar view with the anchor opened. Fig. 3 is a side view of the anchor in operation.

The anchor is preferably made of metal and consists of a tubular shank 5 having T-heads 6 and 7 at each end. The head 6 acts as a journal for the spindle 8 of the fiukes 9, while the head 7 carries at each side headed studs 10 on which are arranged the fiukes 11 but whose movement is limited by shoulders 12 on the T-head 7. These fiukes 11 are flattened so as to dig in to the sand or mud and the greater the strain put upon the chain 13 carried by the shank 5, the deeper the fiukes will penetrate the sand.

The fiukes 9 and their spindle are free to rotate in the head 6 but the spindle is perforated and through the perforation passes the stem let of end fiukes 15 so that when they occupy the folded position shown in Fig. 1, the stem 14 passes through the spindle and retains the fiukes in the position shown in Fig. 1.

When the anchor is extended for use as shown in Fig. 2, the stem 14-is withdrawn from the perforation in the spindle 8, which is then freeto rotate and thrown into the position shown in Fig. 3, and again locked by the stem. The stem 14 is held in its two positions by means of the key 16 which engages one of the slots 17 or 18, the latter when the anchor is extended or the recess 17 when the anchor is folded.

The key 16 is best shown in Fig. 4, where it would be seen that it is adjusted by means of the nut 17 which draws the key into the slot of the stem 14: to prevent its rotation or its longitudinal movement and in consequence the fiukes 15 may be retained in the horizontal position shown in Fig. 1 or turned at a right angle to dig into the sand as shown in Fig. 3.

With an anchor thus arranged, a maximum amount of resistance is secured and when folded, it may be packed in a Very small compartment so that several of these anchors may be carried on a vessel without any serious inconvenience and they will possess suflicient resistance to answer the purpose of several anchors when in use.

It is obvious that the anchor may be otherwise arranged or modified without departing from the essential features above described.

What I claim as new and desire to secure by Letters Patent is,-

1. In an anchor, the combination with a hollow shank, of folding fiukes at each end of same, and a sliding and rotating stem with flu-kes andlocked within the shank.

2. In an anchor, the combination with a tubular shank, of movable fiukes at each end of same, a stem carried within the shank and having fiukes, and locking means for holding the latter flukesflin an operative or folding position.

3. In an anchor, the combination with a tubular shank, of movable fiukes at each end of the shank, a stem within the shank, auxiliary fiukes at the outer end of the stem, and means adapted to lock the movable and auxiliary fiukes in a folded and inoperative position.

4. In an anchor, the combination with a tubular shank, ofT heads at each end of the shank, fiukes carried by each T head, a rotatable and slidable stem carried in a tubular shank, fiukes at the outer end of the stem,

and means connected With the stem for lockand a bolt adapted to enter the recesses and 10 ing the stern so as to retain the fiukes in a lock the stem. 7 folded or an operative position. In testimony whereof I have aflixed my g. 1In aln alnchofr, the corlrlibiration vi lith (2i signature in presence of two Witnesses. tn u ar s an r, o a cross ea at eac cm of the shank, a perforated spindle With flukes THOMAS BUTTERS' at one end of the shank, flukes on studs and Witnesses: carried by the other head of the shank, a JAMEs F.
